Benefits of technology

"The present invention provides a network control circuit with a pseudo hot plug function and a pseudo hot plug method for a network control circuit. This helps to save power and can be applied to various network control circuits. The network control circuit detects the connection status of a network and determines whether to turn off or on the network processing module accordingly. This helps to optimize network performance and saves power."

Problems solved by technology

The network control circuit in a traditional computer always consumes power no matter the connection status of the network is connecting or un-connecting, and it results in a problem of wasting power.

first embodiment

[0014]Please refer to FIG. 1. FIG. 1 shows a simplified block diagram of a network control circuit 100 in accordance with the present invention. As shown in FIG. 1, the network control circuit 100 comprises: a network processing module 110, a network detecting unit 120, and a control unit 130. The network processing module 110 is coupled to the bus interface 140, and the bus interface 140 can be a Peripheral Component Interconnect (PCI), a Peripheral Component Interconnect Extended (PCI-X), a Peripheral Component Interconnect Express (PCI-E), or an Universal Serial Bus. In addition, the network processing module 110, the network detecting unit 120, and the control unit 130 are integrated in a network control chip 150 in this embodiment.

[0015]The network processing module 110 is utilized for executing a network function of the network control circuit 100. The network detecting unit 120 is utilized for detecting a connection status of a network (not shown) connected to the network con...

second embodiment

[0016]In addition, in the present invention, the network processing module 110 and the network detecting unit 120, are integrated in a network control chip 160, and the control unit 130 is externally connected to the network control chip 160 as shown in FIG. 2. For example, the control unit 130 can be a chip set on a motherboard.

[0017]Please refer to FIG. 3. FIG. 3 is a flowchart showing a pseudo hot plug method applied to a network control circuit in accordance with the operation schemes of the network control circuit 100 in the above embodiments of the present invention, wherein the network control circuit comprises a network processing module for executing a network function of the network control circuit. Provided that substantially the same result is achieved, the steps of the process flowchart need not be in the exact order shown in FIG. 3 and need not be contiguous, that is, other steps can be intermediate. The pseudo hot plug method applied to the network control circuit acc...

Abstract

The present invention provides a network control circuit having a pseudo hot plug function and a pseudo hot plug method for a network control circuit. The network control circuit comprises: a network processing module for executing a network function of the network control circuit, a network detecting unit for detecting a connection status of a network connected to the network control circuit so as to generate a detecting result, and a control unit coupled to the network detecting unit and the network processing module, for determining whether to turn off the network processing module according to the detecting result. When the detecting result shows that the connection status of the network is un-connecting, the control unit determines to turn off the network processing module. When the detecting result shows that the connection status of the network is connecting, the control unit determines to turn on the network processing module.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a network control circuit, and more particularly, to a network control circuit having a pseudo hot plug function and a pseudo hot plug method for a network control circuit.[0003]2. Description of the Prior Art[0004]In general, the specifications of the Peripheral Component Interconnect (PCI), the Peripheral Component Interconnect Extended (PCI-X), and the Peripheral Component Interconnect Express (PCI-E) do not support pseudo hot plug function. The network control circuit in a traditional computer always consumes power no matter the connection status of the network is connecting or un-connecting, and it results in a problem of wasting power.SUMMARY OF THE INVENTION[0005]It is therefore one of the objectives of the present invention to provide a network control circuit having a pseudo hot plug function and a pseudo hot plug method for a network control circuit, so as to solve the above pr...
